The effects of iron ore dust on mangroves in Western ...

Anecdotal evidence suggests that iron ore dust derived from industrial shiploading activities in north-western Australia may be more injurious to mangroves than is naturally-derived dust, because of its more angular structure and presumed ability to damage stomatal cells. Abaxial hairs on the most common mangrove, Avicennia marina (Forfk).
